Sadly, in my early days of internet access (year 1998, age 15), I'd have easily fallen for something like this, and acted equally drastically. Knowing what fellow inmates DO to aspie guys in juvenile prison showers, I'd have preferred a quick, permanent way out to having THAT done to me. Not to mention getting in trouble with my parents, who were very strict at the time (but somehow neglected to put restrictions on my internet use). Although if I had a credit card as a teen, I'd probably have paid the "fine", and never told my parents about any of it; or if they found out, lied about someone stealing the credit card number. Imagine that! A credit card saving my life.
Ironically, when I learned the truth, I had to explain to my parents that these e-mails were false. Although their reactions were more like "what the hell is this?", rather than "oh no, they found me!"
